Design of environmental radiation dose monitoring equipment based on GD32E231

In daily life, people often cannot stay away from the influence of radioactive radiation. For example, when they go to the hospital for a CT scan, professional practitioners in particular often need to effectively monitor the radiation dose rate in the environment. Nowadays, small personal dose values ​​are commonly used. It is worn by individuals and the cumulative dose value within a period of time is calculated after regular submission. This project plans to design a model prototype of environmental dose monitoring equipment based on the GD32 domestic chip. It counts through Geiger tubes and uses digital tubes to display dose information in real time. When the dose rate reaches or exceeds the threshold, an audible and visual alarm will be generated. A GPRS module will be considered later. The data can then be uploaded to central management.

Wind turbine tower disaster early warning system

This project uses the LSM6DSOX+STEVAL-MKI109V3 mode for preliminary sensor learning and research, mainly from training the acceleration sensor to detect vibration and recording vibration waveforms, training the gyroscope sensor to detect the vibration direction and offset, and recording the waveform for analysis; combined with the acceleration sensor and the action data of the gyroscope sensor can determine the vibration intensity and direction of the wind turbine tower under various working conditions; in practical applications, the LSM6DSOX sensor is combined with the low-power chip STM32L010RBT6 chip, and the main control board on the local side leads to an alarm relay. The outlet is used for alarm output on the wind turbine tower side. It is connected to the wind turbine scada system through 485 serial port communication to upload the recorded data on the local side to provide real-time feedback on the working status of the wind turbine tower. It can be used to analyze the vibration reverse and wind turbine tower vibration. Swing direction recording can also record and analyze the natural frequency of the wind turbine tower under normal conditions and the natural frequency during faults. The multi-faceted data forms a wind turbine tower disaster warning system that can be sensed in advance;
